PIPE-CONNECTING MEMBER.

Specification of Letters Patent.

Application filed February 28, 1905. Serial No. 247,699. a

T0 aZZ whom it may concern:

Be it known that I, J ULIUs DAVID TSCHOPIK, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Pipe-Connecting Members, of which the following is a specification.

My invention relates to plumbers brass ferrules, soldering-nipples,and soldering-unions, &c.; and its object is to provide a device suitable for ready application to the connections to which it is to be applied and yet having means to enable it to be shipped and handled without injury thereto.

To this end my invention is embodied in preferable form in the article of manufacture hereinafter described, and illustrated in the accompanying drawings.

In the drawings, Figure l is an elevation of a soldering-nipple embodying my improvements; Fig. 2, a similar view showing the protective covering partly removed and the .nipple ready for application, and Fig. 3 a sectional view.

Referring to the drawings, a is the body of a brass nipple, and 5 the stem thereof, adapted to engage a pipeor other part to be connected. This stem must be tinned before soldering it to its connecting-pipe, and it is usual to do this at the time of making the connection. In so doing it is necessary first to clean and file the stem before soldering and then temporarily cover the part that is not be tinned with a 'piece of paper to prevent the solder flowing over upon such part and adhering to it when making the wiped joint to its connecting-pipe.

In my invention the nipple or ferrule is provided for a portion of its length and extending to the end of the stem with a permanent originally-fixed coating of solder or tinning-alloy c. This coating extends along a limited portion of the stem, leaving an untinned portion cl. On this part dis pasted or glued a protective cover 0, of paper or other suitable material. This covering extends over the tinned portion 0 and at the line of junction between the tinned and untinned portions is provided with a weakened or perforated severing-line f, whereby when the ferrule or nipple is to be applied to its adjoining part is the covering torn off at this severing-line, while the remaining part of the covering remains aflixed to the untinned part and prevents the solder from flowing down on said part and sticking to it when the nipple is applied to the wiped joint.

It is necessary that the tinned coating be perfectly protected against tarnishing, soiling, or injury; otherwise it will not be fit for use when it is desired to apply the same.

It is clear that various changes or modifications in the details of the article may be made without departing from the scope of the invention.

Having thus described my invention, what I claim is- 1. As a new article of manufacture, a pipe member having astem adapted to be soldered to a connecting part, and having an originallyafiixed, permanent tinned coating thereon, and having a protective covering for said tinned coating, secured to an untinned part of the stem and extending loosely over the tinned coating and removable therefrom to expose said coating, substantially as described.

2. As a new article of manufacture a plumbers pipe member such as a ferrule, nipple, &c., having a stem adapted to be soldered to a connecting part and having a permanent originally-affixed tinned coating extending along said stem for a portion of the length of the latter, a protective coating affixed to the untinned part of the stem and extending over the coating and having a severing-line at the point of junction of the coated and uncoated portions of the stem, substantially as described.

In testimony whereof I aflix my signature in presence of two subscribing witnesses.

JULIUS DAVID TSOHOPIK.
